Background technique

There are following two types of prefabricated concrete walls with thermal insulation layer in the prior art:

One is the Chinese patent document with the publication number "CN105538500A", which discloses a prefabricated concrete sandwich thermal insulation laminated panel exterior wall and its manufacturing method, including an inner wall layer and a cavity layer that are arranged sequentially from the inside to the outside. , thermal insulation layer and outer wall layer; the inner wall layer is provided with inner distribution reinforcement, the cavity is provided with outer distribution reinforcement, and the outer wall layer is provided with crack-resistant steel mesh; The inner distribution reinforcement, the outer distribution reinforcement and the anti-crack reinforcement mesh are connected to each other through lattice reinforcement. The invention simply and effectively solves the problem of discontinuity of the thermal insulation board at the lattice reinforcement by utilizing the existing thermal insulation board of the laminated board type exterior wall sandwich insulation.

This technical solution is only used for "laminated slab exterior walls"; the insulation layer is poured during prefabrication, which results in low work efficiency and high preparation costs, and it is not easy to guarantee the thickness and uniform quality; the concrete of the inner and outer wall layers The maintenance is divided into two times, and the turning process needs to be added, which is low in work efficiency and increases the production cost; in order to ensure the rigidity and strength of the outer wall, the lattice steel bars must be increased, which increases the thermal bridge effect and reduces the thermal insulation effect. It is necessary to thicken the thermal insulation Compensation of layers, enlargement of steel bars and thickening of insulation layer all increase the preparation cost.

The second is the Chinese patent document with the patent number "ZL2012202129846", which discloses a prefabricated sandwich thermal insulation concrete exterior wall panel, which adopts a composite wall panel integrating wall-insulation-building decoration from the inside to the outside. The body is a load-bearing concrete structure layer, the middle is a thermal insulation board, and the outermost is a building decoration cladding board. The three layers are connected into a whole through thermal insulation connectors, and it is applied to the assembly of integral shear wall structures or integral frame- Composite exterior wall panels with shear wall structure and meeting building energy saving and fire protection requirements. The product is prefabricated in the factory and installed on site, with high production and construction efficiency and guaranteed quality; energy saving and environmental protection, fire prevention and heat preservation, and significant comprehensive benefits.

This technical solution is similar to the existing commonly used technical solutions, but the main problems are that the cost is relatively high, and the detection and inspection of the product is inconvenient, especially its durability inspection is very difficult.

Contents of the invention
